OpenVT

What OpenVT is

OpenVT is free, open-source software for 2D Vtubing, with Linux desktop support as its main priority. It supports Live2D avatar import and two tracking options: OpenSeeFace, which requires a separate executable, and VTubeStudio over Wi-Fi TCP. Transparent windows support alpha-based capture in OBS without a virtual camera or direct framebuffer access. Adjustable filtering can sharpen the scaling of pixel-art models, and multi-window popout controls provide additional ways to operate the software. Models can be shared with VTubeStudio without file changes, while OpenVT-specific settings stay separate to avoid naming conflicts. The project is built in Godot using open-source solutions and aims for VTubeStudio feature parity, excluding complex features such as plugin compatibility and VNet. Precompiled itch.io builds are provided nightly when there are changes, but stability is not guaranteed. On Linux, system-wide keyboard input while the window is unfocused depends on the godot-keylogger extension; some distributions also require the user to be in the libinput group. The repository is marked MIT-licensed, while Live2D rendering depends on the copyrighted Live2D Cubism SDK.
